I have an i7 6 core machine with 16GB of RAM and two external USB.30 2TB HDDs. Are you saying that I should not utilize that hardware? I want to run a media server on my LAN and want to utilize unraid's ability to give me a robust storage space with my extra drives to do so. Also, upon digging into the forums deeply after posting in this thread, I found that people have found this adapter works solving my problem. https://www.amazon.com/gp/product/B07MK6DJ6M/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1 Apparently any AX8817 chipset ethernet adapter works in Unraid. I have ordered one and will report back on its effectiveness.
UPDATE: As promised. I have confirmed that the USB adapter works just fine on a USB 3
